All of the aluminum pipe we carry in stock is Schedule 40 pipe and is 6061 alloy. We can special order 2024 alloy pipe which is about 50% stronger than 6061 alloy. 6061 pipe is commonly used for structural components, frames, machine parts, truck and marine components, marine fittings, electrical fittings and connectors, bike frames, railings, truck racks, etc. 6061 is used for heavy duty structures requiring good strength-to-weight ratio with good corrosion resistance. 6061 is easily cold worked and formed in the annealed condition. Cutting, stamping, bending, spinning, deep drawing, drilling, tapping, etc. are all readily accomplished using standard methods. Schedule 80 pipe is available by special order.
